Computer keep randomly turning off (PSU Failure)?

Just recently my desktop pc has been randomly turning off without reboot, showing blue screens of death and sometimes even showing weird lines on the monitor which requires a reboot to fix. It usually only happens when I play a a fps intensive/moderately intensive games for around 15-20 minutes.

I cleaned the dust out of my system with compressed air but that still did not fix the problem at all. I have a feeling it might be something to do with the PSU failing due to prolonged use (I've had the pc for around 3 years).

If anyone can diagnose and help me with my little problem that would be great.

My specs are:
Windows Home Premium 32 Bit OS
4 GB DDR3 RAM
AMD Radeon HD 5670 1 GB
AMD Athlon ii x2 265 3.3GHZ
ASRock 880GM-le motherboard
Aywun 420W PSU (not a very well known brand)

It sounds like it could be the GPU failing, it also could be the RAM, after that we will have to start testing things one by one. Have you got the crash report from the BSOD, this will give us a good clue.

Yeah it could possibly be any of these components. No I do not currently have a crash report from a BSOD because they were toggled off at the time, but when the next BSOD happens I will read and tell you the crash report.

I doubt its the PSU. They (usually) work or they don't.
When RAM goes bad typically you get nothing on your screen and the system fails to boot afterward.

The failure after 15 to 20 minutes of gaming makes this sound heat related. The CPU will auto throttle or even shut down when it hits 100C. Most likely same for the GPU. A CPU or GPU cooler fan not spinning so well can cause over heating. Hope its the CPU fan as they are cheap and easy to replace.

My xbox360 would get the lines appearing on screen thing too. It was the model that got the "red ring of death" due to overheating MB/GPU....
